WD Internal HDD Reviews

3/4 work great! 1 DOA.

By Robert

I finally got to install these drives the other day. I've been building a small home server. Anyway, 3 of the 4 drives work perfect. The 4th drive appears to be a manufacturer defect and you cannot plug in the sata port. Besides that, I'd recommend these drives, but the 4th drive needs to be returned for a replacement. I saw another person bought 2 drives and 1 of the drives was also DOA for him.

Each WD 8TB Gold 7200 rpm SATA III 3.5" Internal Enterprise HDD, BH #WEGESHDD8T, has an active acoustic noise level of 36 dBA. That's like a whisper from across the room.
